t think, mother," he cried. "We're
going! We're going! Captain Hardy has sent for us!"

Mrs. Harper looked at her son anxiously. His words meant absolutely
nothing to her, for Henry had not told any one of his letter to his
captain. Suddenly she feared that perhaps something had fallen on
Henry's head and momentarily unbalanced him.

"Going?" she said. "Where? What are you talking about?"

"We're going to New York City to help catch German spies," cried Henry,
beginning to dance about again in his excitement. "Isn't it bully!
And we'll catch 'em, too, just as we did the dynamiters."

"I guess you're going crazy," said his mother. Then as Henry continued
his demonstration, his mother said sharply, "You stop right there,
Henry Harper, and tell me what all this nonsense means about German
spies and New York and Captain Hardy. You know very well that Captain
Hardy is in Washington with the army."

Henry at once calmed down and took a grip on himself. "Yes, mother,"
he said. "Captain Hardy was in Washington, but he is going to New
York----"

"How do you know?" interrupted Mrs. Harper impatiently.

"He just telegraphed me----"

"Telegraphed you!" said the incredulous Mrs. Harper. "What would
Captain Hardy be telegraphing to a youngster like you for, I'd like to
know."

"In answer to my letter----" began Henry, but again his mother cut him
short.

"Your letter?" she said. "What letter? I didn't know that you had
written him a letter."

"You see, mother," said Henry patiently, "when I read in the newspapers
the other day that the Germans had found out about the sailing of
Pershing's men, and had sent submarines to lay in wait for them out in
the ocean, the idea came to me that perhaps the wireless patrol could
help to discover----"

"Henry Harper, I hope you never had the impudence to suggest that you
youngsters could----"

"I did, mother. But I don't think it was impudence. I wrote to Dr.
Hardy and asked if the wireless patrol couldn't help catch the spies
who are sending news to Germany."

"Well of all things!" ejaculated Mrs. Harper. "What will you infants
do next? Offer to relieve the President of his job?"

"Well, we did catch the dynamiters at the Elk City reservoir,"
protested Henry defensively. "And we did it after the state police and
the national guards had failed. I don't see why we can't help catch
German spies in New York just as well as in Pennsylvania."

"Humph!" said Mr
